Occupational crosswalk, data and language requirements
Maria Forthun Hoen
Abstract: In this technical paper, I describe how I create a crosswalk between the standard occupational classification systems in Nor-way and the U.S. I use the "Standard yrkesklassifisering, NOS C521" ("STYRK") from 1998 for the former, and the occupational taxonomy from the 2000 Census of Population and Housing for the latter. The crosswalk enables linking of Norwegian occupa-tions to worker and occupational characteristics from the O*NET database under the U.S. Department of Labor. From O*NET data, I construct a "language index" that ranks all occupations by the required level and importance of majority language skills, as well as several cognitive abilities measures, as explained in section 2.
In section 3, I explain how I obtain data on workers’ occupa-tions from Norwegian register data starting in 2003. Occupation was gradually introduced as a variable in the Employer-Employee Register for a selection of employers in 2003. I supplement with occupation from the Wage Statistics survey from Statistics Nor-way, and with translations of position codes into occupations for employees in the public sector.
I end with a brief description of the construction of mappings between the three standard industrial classification systems in the Norwegian register data after 1994 (SIC94, SIC2002 and SIC2007) in section 4.
The occupational crosswalk is attached as a table in the ap-pendix. For other formats (csv, excel, dta) or further details on any of the technical issues, please contact the author.

1 Occupational crosswalk
Albeit the quality and quantity of Norwegian administrative regis- ter data is excellent, there exists no complete and consistent data on occupation-specific characteristics. I therefore use data provided by the O*NET database.1 To link O*NET data to Norwegian occupations, I manually construct a crosswalk from the Norwegian standard occupa- tional classification system ("Standard yrkesklassifisering, NOS C521"
from 1998, or "STYRK", henceforth) to the occupational taxonomy of O*NET. To go from STYRK to O*NET is however not straightforward.
In between there are several steps, illustrated in figure 1: STYRK is a modified version of EU’s International Standard Classification of Oc- cupations, ISCO-88(COM), which again is a modified version of the International Labour Organizations’s system ISCO-88. ISCO-88 can be mapped to the occupational classification system used in the 2000 Census of Population and Housing ("CEN2000") with a crosswalk fa- cilitated by the National Crosswalk Center ("NCC"). CEN2000 can again be mapped to the U.S. Standard Occupational Classification sys- tem ("SOC") as of 2000, which is the basis for O*NET’s occupational taxonomy ("O*NET-SOC"). 120 of the 821 SOC occupations are split into more detailed O*NET-SOC occupations, making a total of 1,094 unique occupations. In contrast, CEN2000 consist of 509 occupations and STYRK of 349.2
The constructed crosswalk maps STYRK to CEN2000, and is based on the NCC-crosswalk from CEN2000 to ISCO-88.3 I use CEN2000 because it resembles more the Norwegian system than either SOC or O*NET-SOC, and therefore makes a more transparent mapping. I do some small changes to the NCC-crosswalk as follows. I make almost identical titles identical so they can be matched with Stata. I add one missing match from CEN2000 to ISCO-88 (136 Civil Engineers to 2142 Civil Engineers), change one mapping (146 Mechanical Engineers from 9999 No Census Equivalent to 2145 Mechanical Engineers), and cor- rect some typos (3469, which does not exist, to 3460, 7233 to 7243 when mapped to 732, and 7422 to 7442 when mapped to 871).4 Be- cause the NCC-crosswalk goes from CEN2000 to ISCO-88, i.e., maps

each CEN2000 to one or more ISCO-88 occupation(s), and I need the opposite, I do some further adjustments to the crosswalk (see step 5 below). I use the following algorithm to create the crosswalk:5
1. Match STYRK to CEN2000 occupations with identical titles. Re- turns 28 matches out of 349 STYRK occupations.
2. Match unmatched STYRK to ISCO-88 occupations with identical titles. Further 166 STYRK codes are matched to ISCO-88 and will be mapped to CEN2000 in step 4. 155 STYRK remains un- matched.
3. Manual adjustments of the NCC mapping, either when identical ISCO-88 and STYRK codes represent different occupations, when CEN2000 occupations do not have O*NET data, or when there is a better match from STYRK to CEN2000 than via ISCO-88.6 4. Map STYRK to CEN2000 via ISCO-88 (except those adjusted
above) with the NCC crosswalk.
5. Drop "redundant" matches and adjust inappropriate mappings due to the "wrong direction" of the NCC crosswalk.
5Complete Stata-code available upon request.
6I drop armed forces and "Unspecified" due to missing O*NET data.
I aim at making the crosswalk as transparent, consistent and sim- ple as possible. In step 3 and 5, I map occupations with similar descrip- tions in Statistics Norway (1998) and "2000 SOC codes, titles, and defi- nitions" fromhttp://www.bls.gov/soc/#archives or the Occupa- tional Outlook Handbook from Bureau of Labor Statistics.7 To sim- plify the mappings to O*NET characteristics and increase the trans- parency of the crosswalk, I minimize the number of CEN2000 matched to each STYRK and delete many of the returned matches from the NCC-crosswalk. Finally, I manually check that all matches are sen- sible, i.e., that each STYRK is mapped to one/more similar CEN2000 occupation(s), and that the language requirements assigned by the O*NET characteristics seem reasonable.
All countries in the European Union use occupational classification system similar or equal to ISCO-88(COM). To link O*NET data to oc- cupations in these countries, it should be relatively straightforward to modify the current crosswalk. A few caveats are however called for:
1. The aim of the crosswalk is to connect language requirements from O*NET to Norwegian occupations. I therefore emphasized language similarities when in doubt of the best match.
2. I put less effort in finding a good match for small occupations in the Norwegian labor market, e.g., 7422 Boat Builders, and 7423 Basketry Weavers, Brush Makers and Related Workers.
3. Several CEN2000 occupations are not mapped to STYRK because of the direction of the crosswalk (from STYRK to CEN2000). The crosswalk should therefore be used with caution in the opposite direction. At the minimum, one should check that central occupa- tions for the relevant study are not lost due to missing mappings.
To further map STYRK from CEN2000 to O*NET-SOC, I first use a mapping from NCC between CEN2000 and 2000 SOC.8 I then sim- ply aggregate the more detailed O*NET-SOC occupations into the 2000 SOC and average over their O*NET characteristics. Whenever sev- eral CEN2000 occupations are mapped one STYRK in the constructed

xwalks/. Three SOC codes are missing in the crosswalk and therefore added manually: 11-3040 Human Resource Managers to 013 Human Resources Managers;
19-1020 Biologists to 161 Biological Scientists; and 43-6014 (instead of 43-6019, which does not exist) Secretaries, Except Legal, Medical and Executive to 570 Secretaries and Administrative Assistants.
crosswalk, I again average over the O*NET characteristics. I am left with one value of the different O*NET characteristics per STYRK.
Next, I explain more about these characteristics and how they are used.
2 O*NET
In what follows, I describe how I use O*NET data to construct the "lan- guage requirement index" that instruments for immigration into occu- pations in Hoen (2018). The U.S. Department of Labor supplies com- prehensive data on worker and occupational characteristics through the Occupational Information Network (O*NET) Resource Center. The O*NET data are organized within the Content Model, which is orga- nized into six main domains divided into sub-areas. The data build on surveys of workers, employers and job experts on information about workers and occupations within jobs, sectors and industries.9 The database version that I use (Version 9.0 from December 2005) contains O*NET data for 974 O*NET-SOC occupations, and is the latest version with the 2000 SOC taxonomy. Table 1 displays the different elements of each measure explained in the subsections below.
I use survey data on worker skills, knowledge and abilities, and oc- cupational requirements from the domains "Worker Characteristics",
"Worker Requirements", and "Occupational Requirements". A score between 1 and 5, where 5 is "extremely important" and 1 is "not im- portant", is given to each question: "How important is (characteristic) to the performance of (occupation)?". Further, the survey asks, on a scale from 1 to 7: "What level of (characteristic) is needed to perform (occupation)".10 In the language measure, I combine the importance and level of each element, whereas in the other measures, I mainly use level (following Deming (2017), among others.)
2.1 Language requirements
I measure occupations’ language requirements as the average of the importance and (rescaled) level of "Speaking Skills", "Writing Skills",
9For more information, see "Content Model Outline––Detailed including descrip- tions" found athttp://www.onetcenter.org/content.html
10The questionnaires can be found at http://www.onetcenter.org/
questionnaires.html
"English Language Knowledge", and "Foreign Language Knowledge".11 I include the latter two because I want to capture requirements forma- jority language skills (i.e., English in the U.S., and, correspondingly, Norwegian in Norway), and not just communication skills in general.
Requirements for English language knowledge is positively correlated with majority language requirements in the U.S., whereas require- ments for foreign language knowledge is negatively correlated. I there- fore add speaking and writing skills together with English language knowledge, and subtract foreign language knowledge. I average over the four characteristics and standardize to mean zero and standard de- viation of one. This "language index" is then used to order occupations’
by their degree of language requirements in Hoen (2018).
2.2 Alternative language indices
For robustness checks in Hoen (2018), alternative language indices in- struments for the inflow of migrants into occupations. Two of them are equal to the index described in section 2.1, but without English lan- guage knowledge, and without English and foreign language knowl- edge, respectively. The third is constructed from worker abilities, and is the average of four verbal abilities, similar to the language measures in Peri and Sparber (2009) and Ottaviano et al. (2013), see table 1.
2.3 Cognitive abilities and social skills
In Hoen (2018), I use several measures for cognitive abilities and so- cial skills. In particular, I construct a "cognitive abilities index" of the 21 worker characteristics categorized by the O*NET Content Model as
"Cognitive Abilities", and one alternative index without the four verbal abilities discussed in section 2.2. The index is very similar to Peri and Sparber (2009), but with a few more abilities included. Further, I use the "Non-routine abilities" measure, which captures required mathe- matical competence, and the "Reasoning abilities" measure from Dem- ing (2017), and the "Abstract tasks" (non-routine cognitive) measure
11"Speaking––Talking to others to convey information effectively"; "Writ- ing––Communicating effectively in writing as appropriate for the needs of the au- dience"; "English (Foreign) Language––Knowledge of the structure and content of the English (a foreign (non-English)) language including the meaning and spelling of words, rules of composition and grammar(, and pronunciation)."

3 Occupations in Norwegian register data
In this section, I describe how I improve the quantity of the occupation variable in the Norwegian Employer-Employee Register ("Arbeidstak- erregisteret"). Registration of occupation was introduced in 2003, but only for a (non-representative) selection of employers.12 For several years, occupation was missing or recorded erroneously for a large part of the observations, see table 2. Further, many public and maritime employers were exempted from reporting occupation, and instead re- ported position codes according to sector-specific position taxonomies.
However, all the taxonomies are mixed together and registered as the same seven-digit occupation variable in the register data, making it difficult to disentangle occupations from positions.
To identify occupations from the occupation variable, I look at the first four digits. These digits represent the STYRK code whenever it is recorded as an occupation. The three last digits specify even more detailed occupation. For position codes, the first three digits represent sector (001, 002 and 003, for municipality, state and maritime sector, respectively) and the four last the position code. No STYRK code begins with 001, 002 or 003, hence the first four digits uniquely identifies an occupation whenever they match a STYRK code.13
In some instances it is possible to translate sector-specific position codes into occupations. This should however be done with caution as positions are not directly comparable to occupations. Positions are linked to wage payments, tenure and so on, rather than tasks and work content as with occupations. Workers within an occupation have more or less the same formal and informal skills, whereas workers within a position primarily share salary.
I construct the occupation variable in Hoen (2018) in the following way. I primarily keep occupation from the Employer-Employee Reg- ister when the first four digits corresponds to a STYRK code. I then exploit that many spells have occupation in the Wage Statistic from
12Employers report their employees’ occupation.
13In the early years, many entries identifies neither an occupation nor a position, possibly due to erroneous registration after the introduction of a complete new sys- tem.
Statistics Norway.14 For the remaining observations without occupa- tion, I translate, whenever possible, positions inferred from the four last digits of the occupation variable from 1) the Employer-Employee Register, and 2) the Wage Statistics. 225 positions in the state posi- tion taxonomy ("Statens stillingskoder") are translated into 76 differ- ent occupations. I have not been able to find complete mappings for the municipality and maritime sector. These positions are hence left unmapped.
In 2003, the first year of registration, 43.5 percent of the observa- tions in the Employer-Employee Register have a valid occupation iden- tified from the first four digits of the occupation variable. The share increases to 46 percent when I add occupation from the Wage Statis- tics. Translating state position codes into occupations increases the share further up to 55.1 percent, see table 2. The percentage of spells recorded with a STYRK occupation increases gradually over time, and in 2011, the above algorithm gives 98 percent valid occupations among the employment spells. The number ofworkerswith a valid occupation is however higher, as many workers have several employment spells within a year. In Hoen (2018), I end up with occupations for roughly 80 percent of the sample, based on workers’ main occupation in 2005, and in addition assigning workers their occupation from another employ- ment spell within the same firm and year. Main occupation is given by the latest full-time job or the part-time job that generated the largest labor earnings that year.
4 Industry crosswalks
In 2002 and 2007, new versions of the Standard Classification Sys- tems were introduced. In order to use data spanning over these years, a translation between the systems is needed. Statistics of Nor- way provides such translations where codes from the outgoing system (SIC1994 and SIC2002) are translated into several, more detailed in- dustries of the coming system (SIC2002 and SIC2007). Ambiguity arises regarding which detailed industry in the succeeding system to

replace for an old industry. I made two mappings from the old systems to unique codes of the new systems with the steps explained below.
Both transitions are available from the author upon request.
4.1 From SIC94 to SIC2002
The transition from SIC94 to SIC2002 was rather limited. Some indus- tries changed codes or names, some were split into more detailed indus- tries, a few new industries was introduced, and some old were deleted.
Whenever one SIC94 industry match two or more SIC2002 industries in the translation from Statistics Norway,15 I keep the SIC2002 with identical title.16 When all suggested SIC2002 titles are different from the SIC94, I keep the largest industry in the Employer-Employee Reg- ister in 2002 (the first year with the new system SIC2002 in place). All matches result in an industry in 2002 that counted for at least 50% of the employment spells in 2002 among the possible SIC2002 industries.
15http://stabas.ssb.no/CorrTabFrames.asp?ID=5606001&Language=en
16A few minor adjustments of the titles were needed in order for them to match exactly.
4.2 From SIC2002 to SIC2007
The renewal of SIC2002 was more extensive with numerous matches for every SIC2002 in the succeeding system. Several manual adjust- ments were needed to match similar but not identical industry titles (available upon request). For the rest of the industries, I keep the largest of the matched industries in 2009 (the first year with SIC2007 implemented). Finally I look through all the matched industry codes and check that the mapping is reasonable.
